Transistor ?

  1. Mar 13, 2004 #1
    The emitter current in a certian npn transitor is 8 mA. If .8% of the minority carrier injected into the base recombing with the holes, find the base current , collector current and the exact value of alpha

    i am not sure how to get this started

    still struggling and REALLY don't know how to go about this problem

    As you know IE = IB + IC
    From the text I would gess that IB = 0.8% from IC, so just substitute in the first equation and you should find alpha
